During the 30-plus years of her showbiz career, Janet Jackson has proved herself a master of reinvention. From her early days as a fresh-faced kid on "Good Times" and "Diff'rent Strokes" to her long, sleek "Rhythm Nation" 1814 look to her red curls for "The Velvet Rope," Janet has inspired countless makeup and hair trends. But that doesn't mean she's self-confident. "I had a very difficult time in my twenties," the 44-year-old has told journalists. "It was hard for me to look in the mirror and find something that I liked about myself." But with 10 albums and movies such as "For Colored Girls" under her belt, Jackson is finally seeing what everyone else always has. "I never really liked my smile before," she said. "[But now] I feel a warmth there that I never saw before."
